To all whom it lmoy concern:

Be it. known that I. oincn'r H. Gorp, :i oitizen of the United States, residinicr at Chi* cago, in the eounty ot Cook and State ot' illinois` have invented eertiiiii new and use` lul Improvements in Convertible lleiitinfb` Systems, of whieh the following is a Speelhcation.

My invention relates to improvements in heating sytenis, especially ot' the direet steam i lie-ating type.

A main object ot my invention is to provide such a system, which may be eoiiverted at will from a dii-eet high pressure and normally closed system to a low pressure, open i system in which the rate ot' supply oit the j heating medium is automatically controlled by the thermostatio condition of said heati ing medium Within said system, and vice versa. This and other objects as hereinater explained are attained by iny invention, which is more specifically set forth in tho claims herein and which is shown in a oon- 'venient embodiment. thereof in the hereto attached drawings, in which s. liigurel'shows, diagrainmatically, a oomg plete heating system. Fig. 2 is sectional l system, I hereinafter refer to it as such, but

do not thereby necessarily limit myself to 1 set in the position shown in Vig. the syssuch application.

' Referring to the aeeompiinying drawings,

for carrying the heating,` medium, which tis a main supply pipe, sueh as a train-pipe, i

for Convenience, but without.v limitation, l

hereafter refer to as steam.

2 1s a. feed-pipe tor eoni'lueting the heatine` medium through the hand-operated to the easing otl the automatie control di j vice ft, from whirh it passes through the pipe into the elre'ulatintv pipes i and S and hack through the return t).

Vhen the parts a re in the position shown in tliiongli the diapliragini-liiiniher ll. to the atmosphere. l

'the .fusioni liroadl)v and the eoiitiollingdeviee are generically the. .saine iis, shown in my Patents Nos. Todi-llo and Ti'l,ti28, the 4controllingV device eoni,ifisinel an expansible diaphragm lo exposed within the diaphragm easing t, which is adapted to move the stein ttt. 'lhis stem engages a lever-arm li' mounted upon the spindle t5. which extends through a suiialile sluiting-box and through the partition ttl into the inlet chaml i`r it) ol the easing l. Within the inlet'l chamber f2() is a lever 2t. wliieh is also rigidly secured to the spindle 1S and engages a valviLstein 32. whieh Carries :i valve Q3 adapted to elose :i port Q which connects the inlet chamber 2O with the pipe El extendingl ljietween the valve and the easing et.

2l is :i three `way ook mounted in the casing lt). adapted to he operated hy the eX- teriial handle 25 and arranged to alternately Close eeniinunieatioii between the system of i'ii'eulatino pipes and the automatic controllin;` devii'e, while opening;` Communication between the eiri'ulating pipes and an automatio steam-trap, and vine versa. This steanrtrap is ot a VFamiliar type, eomi'irisine' a diaphragm .t'i, mounted in the easing 27, the ii'iterior otE whieli eonin'iunirates. through the pipe 2S. with :i drip, or blow-oli.y port 2l) leading trom the interior ot the easingr lt). this l lowotl port. is surri'ninded hy a valve, seat itl, which a valve, ill is adapted to close, said valve Il lining Carried liy a stein 32, by means ot whit-h the valve will he closed by thiI expansion o'tt the diaphragm 9G.

lt will thusl he seen that when the parts are ioni will lie in open eommilniiation with tho :itiiiospliere through the drip pipe lil. Clonseipienily, the steam within the system can never ixi'eed atmospheriix pressure, and tho diaphragm l5 will expand under the temperature ol' steam at atmospheric` pressure to .shut otl' the intlow Vtrom the train-pipe to the system. through the inlet` eliamlier 20, and suoli i-oudition will lie eonst'antly i'iiaintained. l l'` however, it he desired to lill the eireiilatingr pipes with steam at` trainepipe pressure, the. ILway roelir @l will he moved to the position `iliowu in Figi". -fl-, whereupon. eon'iuiuniration between the easing; 'ttl and the roniiei-ting pipe. ll will he olosed. the autoii'iatio rontrollinir device will he ('iit out and the auton'iai'ie trap will he eut. in` whereby tho system is at once converted into va high pressure, closed system, from Twhich the only outletis through the automat-ic trap.

Whenever the trap diaphragm 26 contracts, the valve 31 will unseat, allowing the accumulated vater of condensation to escape, but as soon the Water and cold air has been blown out, and live steam from the circulating system surrounds the-trap diaphragm 26, that diaphragm Will upand and close the valve 3l. llhe valve tv n its controlling` thermostat therefore restricts the outflow of the heating medium, thus causing rise of pressure therein, the thermostat being preferably set so that substantially no steam escapes.

ln Fig. i have, for convenientillustration, shown one modification, in whicha tee tOi 1s substituted for the casing- 10 and connects, through a valve with a pipe leading to the automatic trap 27, and a valve 35 is interposed between the tee 101L and the controlling device a. closing the valve 35 and opening the valve 3, the controlling device Will be cut out and the trap cut in, thus giving a high pressure system, While the reverse operation of the valves -Will cut out the trap and cut in the controlling device, thus converting; the system into a low pressure system.

Obviously, as a matter or mechanical skill, expediency and shop practice, various changes in detail may be made, without departing from the spirit of my invention, which broadly contemplates a system of the character described which may be converted, at Will, from a louv pressure system, normally open, to a substantially closed, high pressure system, and vice versa. Thus, it will be seen that l am not necessarily limited either to the exact form or arrangement of valves, to the use of an automatic trap t0 the. use of any precise form of controllingD apparatus. So, also, it Will be seen that, While it isnecsary to cut o the normally open outlet in order to produce a lflgh pressure system, for obviously there can be no high pressure so long as the system is in free communication With the open outlet, it is not essential that the automatic trap be cut out v/ ot opera tion when the device is changed to a low pressure system, for obviously, with one normally open outlet, it does not materially matter Whether the system is also in communicationV With a second outlet `Which is adapted to be'closed by an automatic device.

It will be noted 'that this present application is limited to the subject'matler pointed out in the claims which relate to a system having two outlets, butin, disclosing such subject matter it Will be seen that -l also disclose, broadly, certain inventions and improvements relating to an interchangeable high and low pressure system which the subject matter or" my c o-pendii'ig appliceases cations No. 245,311 and 242,921, and alA though application No. 245,311 has been filed subsequent to the present application, ithas been deemed desirable, in viewA of the fact that said. applications are both copending with the present application, that the broad claims upon such inventions here -irom this present application certain allowed broad claims covering the suLJectmatter connnon to the ldevices disclosed herein and that disclosed in said application Xo. 245,311; .ther dol claim the specific inode of r1 tricting the discharge ot' the h iting .me lum from the system which consists in making the outletof the system so small relative to its inlet that high 4pressure may be temporarily maintained in the system even though the'outlet be in direct communication with the atmosphere; for combinations containing this feature are specifically claimed in my pending application Serial No, 268,908.

By the term voutlet or discharge device used in the claims, l intend the devices and outlet passages generally conducting the condensed heating medium from the system after it has performed its function therein. When used to designato the instrumentalit-ies connected with pipe 34, these terms are intended to include the valves as. well as the thermostat or. any equivalent devices.
